We present an extensive lattice study of the physical properties of mesons, composed of a heavy, H, and a light, q, quark, at β = 6.4 on a 243 × 60 lattice, using the Wilson action in the quenched approximation. We have studied the mass spectrum an

We present the results of a calculation of the Bs-Bd and B∗-B mass differences and of the mass of the ΛB on the lattice, obtained using the expansion in inverse powers of the heavy-quark mass. We find MBs − MBd = (71 ± 13 − 16) MeV, MΛB −

Two experiments were conducted to examine reproductive and endocrine responses of ram lambs to exogenous glucose. In Experiment 1, three ram lambs (6 mo of age) received 100 ml ip of saline (0.9%) daily and three animals received 50 g glucose (100 ml

Recent results for semi-leptonic decays of $D$ and $B$ mesons at $\beta=6.4$, using the Wilson action, and at $\beta=6.0$, using the Clover action, are reported.

We present the results of a numerical calculation of semi-leptonic form factors relevant for heavy flavour meson decays into light mesons, at $\beta=6.4$ on a $24^3 \times 60$ lattice, using the Wilson action in the quenched approximation. We obtain

A one-link momentum-dependent Yukawa interaction is introduced in a lattice sigma model, using both naive and staggered fermionic formulations. The resulting spectrum of doubled species is examined, and the implications for lattice electroweak models

Efficient methods are described for calculating the various “hadron” (fermion bilinear/trilinear) propagators for free lattice fermions. For lattice sizes typical of current Monte Carlo calculations, the large finite-size effects are investigated

We study the spectra of 2-dimensional U(1) and SU(2) lattice gauge theories with quarks by the quenched Monte Carlo method. Masses of the lowest-lying pseudoscalar and scalar mesons in these theories are calculated for a range of quark masses. We fin

Results of two different calculations of the decay constants (fP) of heavy pseudoscalar mesons (P) are presented. The first calculation uses the static approximation for the heavy-quark propagator, and the second uses the conventional technique where
